PASCO’s Discover Freefall System can be used to drop almost any small object by attaching a small steel washer with a small adhesive pad (both are included in the system). Using an electric switch, timing is started automatically, just as the object is dropped. And the Time-of-Flight Pad stops timing when the object strikes it.
Students can investigate the effect of air resistance on acceleration. In addition, students can drop objects of the same size but different mass to study how object mass affects terminal velocity during freefall. The drop box has a magnetic mount for attaching to metal frames in ceilings.
How It Works
Any small object can be dropped with the Discover Freefall System by attaching a washer to the object with an adhesive pad (both included). The Drop box’s active feedback loop measures the magnetic field and adjusts current to null field and release ball in less than 1 ms once the electric switch is pressed.
